Hi, I noticed that you have a lot of information on the Pettigrove family.  I am trying to track down information on Martha Pettigrove.  (Daughter of Drucilla and John) 
We are not related by my Granny knew her as a girl when she lived in Lydd, Romney Marsh in Kent and when I was a girl she told me many 'Martha stories' (as they were known) of the little traveller. I even taped a few of the tales and still have this.  My Granny was very fond of her and 'Martha stories' will always one of the best memories I have of my Granny!  
I noticed that you mentioned her daughter was still alive and I do hope she still is!  It would be amazing to get in touch with her and pass on a recording of the stories I have if you are able to point me in the right direction,
Many thanks, Jo
